Circuit Considerations for EPC2TI32N

Configuration & Interface

The EPC2TI32N is designed to configure Altera SRAM-based FPGAs:

Configuration Interface: Easy-to-use 4-pin interface to Altera FPGAs[reference:21]
JTAG Interface: Built-in IEEE Std. 1149.1 JTAG interface for in-system programming, boundary-scan testing (BST), and configuration[reference:22]
Programming Support: Supports programming through .svf, .jam, .jbc files, and Quartus II software with USB Blaster, MasterBlaster, or ByteBlasterMV cables[reference:23]
Configuration Compatibility: Compatible with Altera APEX 20K, APEX II, Arria, Cyclone, FLEX, Mercury, Stratix, and Stratix II devices[reference:24][reference:25]
nINIT_CONF Pin: Allows INIT_CONF JTAG instruction to begin FPGA configuration[reference:26]

PCB and Power-Supply Guidance

Configuration memory performance depends on layout, bypassing, and component selection:

Supply Voltage: VCC supply voltage from 3V to 5.5V; supports both 3.3V and 5.0V operation[reference:27]
Bypass Capacitors: Place decoupling capacitors close to VCC and GND pins to minimize noise
JTAG Connections: Ensure proper pull-up/pull-down resistors on JTAG signal lines as recommended in the configuration handbook
nINIT_CONF Pin: Use for initiating FPGA configuration when required
Layout Considerations: Keep configuration signal traces short and properly terminated for reliable configuration
Thermal Management: TQFP-32 package with 7mm × 7mm footprint; ensure adequate airflow for heat dissipation
Verify the recommended PCB footprint from the official datasheet before production
